Detailed explanation-1: -Which of true of aerobic respiration but not true of anaerobic respiration?-CO2 is produced.

Detailed explanation-2: -Aerobic respiration uses oxygen. Anaerobic respiration is respiration without oxygen; the process uses a respiratory electron transport chain but does not use oxygen as the electron acceptors.

Detailed explanation-3: -So aerobic respiration produces 6 molecules of water. Anaerobic respiration can be either alcoholic fermentation (that produces alcohol and carbon dioxide) or lactic acid fermentation (that produces lactic acid). Either form of anaerobic respiration does not produce any water molecules.

Detailed explanation-4: -However, in anaerobic respiration, the breakdown of glucose is incomplete. The end product of anaerobic respiration is lactic acid instead of carbon dioxide and water. This process occurs in oxygen debt. Hence, the amount of oxygen required to oxidize lactic acid to carbon dioxide and water is not present.

Detailed explanation-5: -The products of anaerobic respiration are lactic acid, carbon dioxide, and water. Anaerobic respiration is the breakdown of glucose in the absence of oxygen.
